Definitions

  • the invention relates to the combination of an elongated I- shaped channel and a pair of air filter components configured to cooperate therewith to prevent bypass of air flow between adjacent edges of the pair of filters.
  • Air handling units which include as a part thereof a heat exchanger and a fan, which cooperate to direct air to be heated and/or cooled across the heat exchanger for direction to an enclosed area to be heated and/or cooled. It is well known to make such air handing units in a modular manner, wherein the modular units have common dimensions which allow them to be assembled in a variety of combinations depending upon the size of the installation and the location of the installation.
  • the basic modules of such a system include a fan module, which typically includes a centrifugal fan and motor assembly, and a coil module, which includes a heat exchange coil, and usually a filter of some type.
  • such modular construction includes a substantially rectangular framework, which supports the inner components of the module and supports outer walls for enclosing the components.
  • structure may be mounted to the framework adjacent to an opening which communicates with the heat exchange coil, which serves to receive and support a filter.
  • a single air filter element may be of sufficient size to be received in the mounting structure to filter the air passing thereto.
  • Such heat exchange elements typically comprise filtration material contained within a rectangular framework extending around the perimeter thereof. When two or more filter element are used flat edges of adjacent rectangular elements are in abutting relationship with one another.
  • the invention relates to a filter and an insert configured to cooperate with the filter to preclude bypass flow around the filter.
  • the filter includes a rectangular outer frame defining a plurality of planar outer edge surfaces, the filter and edges each having a front side and a back side.
  • the filter is configured to be installed in an application with at least one of the planar edge surfaces forming an abutting intersection with a second planar surface.
  • the planar edge and the second planar surface each have substantially the same thickness and the same predetermined length at the abutting intersection.
  • the insert includes a longitudinally extending planar central wall section configured to be positioned between the planar edge of the filter and the second planar surface.
  • the central walls have substantially the same length and the same thickness as the one planar edge and the second planar surface.
  • the central wall has a front edge adjacent the front of the filter and a back edge adjacent the back of the filter.
  • the insert further includes two end walls, one of the end walls being attached to each of the front edges and back edges of the central wall section. Each of the end walls extends substantially perpendicularly to the central wall section and extends substantially the entire length thereof. The end walls each have a width sufficient to prevent air flow through the abutting intersection.
  • Figure 1 is a perspective view of a heat exchange module having air filters mounted thereto which incorporate bypass inserts according to the present invention
  • Figure 2 is a smaller scale view similar to Figure 1 showing several filter elements and the bypass insert of the present invention partially disassembled;
  • Figure 3 is an enlarged showing of the region identified as Figure 3 in Figure 2;
  • Figure 4 is an enlarged showing of the region identified as Figure 4 in Figure 2;
  • Figure 5 is a side view a bypass insert according to the present invention;
  • Figure 6 is a perspective view of a short length of the bypass insert of the present invention;
  • Figure 7 is an end view of the bypass insert illustrated in Figure 5; and Figure 8 is a cross-sectional view of the bypass insert of the present invention in cooperation with a pair of filter elements.
  • a coil module 10 for use with an air handling unit including filter bypass inserts 32 according to the present invention is illustrated in Figure 1.
  • the coil module 10 includes a substantially rectangular casing defined by a structural framework having eight corners 14 interconnected by a plurality of horizontally and vertically extending structural elements 16.
  • the framework defined by the corners and the structural elements 16 is adapted to removably receive a plurality of outer panels as is well known in the art. None of the panels are shown in the illustration in order to facilitate a clear showing of the coil 18 in the interior of the module.
  • a fan module In operation with the panels installed, a fan module will be mounted in fluid communication with the coil module to effect the flow of air to be cooled into the coil module 10, and across the heat exchange coil 18 supported therein in the direction from right to left, as viewed in Figure 1 and as represented by the arrow 20.
  • the opening through which the air flows prior to passing across the heat exchanger 18 is a rectangular opening defined by two spaced pairs of the structural elements 16, one pair extending horizontally and the other pair extending vertically.
  • the horizontally extending structural elements 16 each defines planar surfaces 22 to which are attached elongated filter mounting channels 12.
  • Figure 1 illustrates three separate rectangularly shaped filter elements 24 received in upper and lower filter mounting channels 12 and having vertically extending filter restraining channels 26 attached to the ends of the channels 12 to thereby retain the filter elements in their desired position.
  • the filter elements 24 are generally rectangular in shape and are shown in a relatively simplified manner in the drawing figures. It is well known in the art that such filters are available in a variety of filtration capabilities and sizes. Typically such filters include a filter media, which is enclosed by a rectangular outer support structure, which generally defines flat outer walls. The horizontally extending walls are generally indicated by reference numeral 28 in the drawing figures and the vertically extending walls are generally indicated by reference numeral 30. As is best seen in Figures 2, 3 and 4, the filter mounting channels 12 are attached to upper and lower structural elements 16 and define substantially U-shaped channels 32, which are adapted to receive the horizontal top and bottom filter walls 28 therein.
  • the filter bypass insert 32 is a vertically extending elongated I-shaped element which preferably is formed in one piece from an extruded plastic material such as poly-cinyl- chloride (PVC).
  • the insert 32 includes an elongated central web section 34 and a pair of perpendicularly extending end sections 36, which are attached to the central section 34 and spaced from one another by a distance substantially equal to the thickness of the filters 24.
  • the lower end 38 of the filter bypass insert 32 is sized such that the lower ends of the end sections 36 rest upon the top edges 40 of the vertical walls 41, which define the filter mounting channels 12.
  • the outer walls of the central webb section 34 are configured to engage the vertical filter walls 30 of a pair of adjacent filter elements 24.
  • the end sections 36 are of sufficient width such that they extend well beyond what would have been the intersection plane of a pair of adjacent filters 24 to thereby assure that no bypass air will pass between adjacent filters when filter bypass inserts 32 are assembled along with the filter elements in a multiple filter installation at each of the transition points between adjacent filters.
  • bypass insert may be installed to receive the edge of the filter and the structure of the abutting wall to thereby prevent the flow of air therebetween.

Abstract

La présente invention concerne un filtre (24) et un insert (32) configuré pour coopérer avec le filtre (24) afin d'empêcher un débit de dérivation autour du filtre (24). L'insert (32) comprend deux parois d'extrémité (36), l'une d'elles étant fixée à chacun des bords antérieurs et postérieurs de la partie de paroi centrale (34). Chacune des parois d'extrémité (36) s'étend de manière sensiblement perpendiculaire à la partie de paroi centrale (34) et étend sensiblement la longueur totale de cette dernière. Les parois d'extrémité (36) possèdent chacune une largeur suffisante pour empêcher la circulation d'air à travers l'intersection adjacente.
